My 11 month old daughter is constantly eating paper and cardboard - you basically can’t leave a book near her without finding chunks taken out of it and I’m always picking bits of cardboard box out of her mouth. I know babies like putting things in their mouths and she’s probably teething but I don’t remember my older daughter actually gnawing on things to this extent, just mouthing them. It’s like living with an hamster! Anyone else’s child done this?
